Hey, I had my struggles with app icons as well when I wrote a small app for myself so I am not really equipped to create the PR (also due to current time limitations). If no one is found for that, I can give it a shot at the end of the year, but I am sure you will find someone sooner than that.

However, I know of a free icon website and have looked through their icons to suggest a few to you:

• Simple Eye https://uxwing.com/view-icon/
• Thin line art eye https://uxwing.com/see-icon/
• Eye in “scanning square” (corners of a square are hinted, the eye is inside; typical “scanning square” for qr code scanners) https://uxwing.com/eye-scanning-icon/
• Binoculars https://uxwing.com/binoculars-icon/
• Spectacles https://uxwing.com/spectacles-icon/
• Happy man with VR glasses https://uxwing.com/virtual-reality-vr-icon/
• Old video recorder https://uxwing.com/video-camera-icon/
• Square with red dot insids and text record https://uxwing.com/screen-recorder-icon/

Uxwings license is amazing: https://uxwing.com/license/ you can use the icons for basically anything and can even alter them.

Personally, I like “Eye in “scanning square”” the most as it symbolizes the technical aspect of scanning/capturing the surroundings.

While I haven’t used it yetis, there is also https://icon.kitchen/ for icon generation.

There’s also https://github.com/revoltchat which is very discord-like but still lacks some vital features that are currently in development like screensharing (if I am not misremembering)

I tend towards: No. I can’t know for sure, but given how pdfs are structured this sounds very difficult.

A workaround might be to automatically place white boxes over those, but you can probably still select the text underneath afterwards.
